COMPARE the Difference With HeatBlocker!

The HeatBlocker Exhaust Insulation System for Diesel and Natural Gas engines is distinguished by state-of-the-art design, materials, and construction. Developed as an Ultra Performance insulation, HeatBlocker provides superior quality and long-lasting durability in the most rigorous of prime power applications. Below is a comparison between HeatBlocker and the industry standard insulation typically manufactured.

Exterior Features:

The HeatBlocker outer shell is constructed of a heavyweight black perfluoroplastic composite fabric resistant to most chemicals and impervious to oils and liquids.l Extreme heat sensitive areas are covered in a high temperature uncoated silica fabric and stainless steel mesh combinaton, sewn with inconel thread. All custom parts have overlapping sealing flaps, stainless steel hooks, and high temperature spring closure.

The typical soft blanket is constructed of lightweight woven fiberglass cloth with silicone coating. Seams are generally finished outside the blanket, using either fiberglass or stainless steel thread, susceptible to heat damage and breakage under extreme temperature and high stress. No overlapping flaps to seal opening are evident, while hooks and difficult to use lacing wire provides closure.

Interior Features:

Every part in a HeatBlocker  system includes a rigidized inconel liner, protecting the 100% high temperature ceramic mat from wicking of liquids and fluids. This patented design allows for the mat to be encapsulated, eliminating the hot spots associated with typical panel construction. Seams are protected from direct contact with engine heat, and inconel mesh creates an air space between the hot face and blanket. Fasteners penetrate only the outer shell, eliminating a conduit for high temperatures to reach the cold face.

Industry standard insulation is characterized by a panel design. Interior seams are exposed, allowing high temperatures to burn out the thread holding the sections together. Outer fabric seams have no protection from the heat on the inner edges, and fasteners penetrate through the entire thickness of the blanket. Mesh liners are usually stainless steel.

Closure System/Fasteners/Edge Protection :

All closure points in a HeatBlocker blanket use either stainless steel or inconel springs. Each closure point has an overlapping flap to reduce outgassing and eliminate the entry of flammable debris. Our unique EdgeGuard, utilizing an extremely high temperature, uncoated silica cloth, protects edges and mating parts from burnouts resulting from radiated heat.

Two methods of closure are most often found on industry standard insulation: stainless steel hooks, or stainless steel capstans. Each uses tie wire to draw the closure points together. This method requires time-consuming lacing, can lead to painful puncture wounds, and will loosen over time as the wire becomes worn or corroded. Standard blankets do not typically use a protective facing for edges and seams.
